CAR-BRAKE.

Specification of Letters Patent.

Patented Dec. 18, 1906.

To all whom it may concern.-

Be it known that I, AMOS KooNsE, residing at Franklin, in the county ofVenango and State of Pennsylvania, have invented a new and ImprovedCar-Brake, of which the followin is a specification.

lly invention'relates to certain new and useful improvements in brakesfor railwaycars and the like; and it primarily has for its object toprovide an efficient and inexpensive brake of the rail-engaging type.

Generically the invention comprises a brake-shoe carrier having aremovable shoe thereon which is ada ted to engage both the top of therail and a so the inner side of the rail-head, so that a greater bearingor friction surface can be had than is possible in shoes of this typewhich engage one end face of the rail-head only.

Again, my invention includes means for mounting the shoe-carrier andtoggle-link devices in connection with the brake-rod for moving the shoeinto and out of engagement with the rail.

With other objects in view than have been heretofore specified theinvention also includes certain novel construction, combination, andarrangement of parts, such as will be first described in detail andthenbe specifically pointed out in the appended claims, reference beinghad to the accompanying drawin s in which 1 O a Figure 1 1s aperspectlve view of a car-truck with my invention applied. Fig. 2 is aside elevation thereof. Fig. 3 is a vertical longitudinal section on theline 3 3 of Fig. 2. Fig. 4 is a detail perspective view of the shoecarrier and shoe detached. Fig. 5 is a diagrammatic side elevation of amodified form of my invention. Fig. 6 is an end elevation of the partsshown in Fig. 5.

Referring now to the accompanying drawings, in which like numerals ofreference indicate like parts in all of the figures, l designates thetruck-frame, 2 the wheels, and 3 the track-rails, all of which may be ofthe ordinary construction and which per 86 form no part of my presentinvention.

In carrying out my invention I secure a pair of brackets or guides 4 onthe truckframe, and the brackets 4 have slideways 4 to receive theshoe-carrier 5, the lower end of which has a flange 5 apertured at 5 toreceive a lug 6 on the brake-shoe 6. The lugs 6 pass through the flange5 and are secured in place by keys 7, as shown in the drawings. Theshoes 6 have wide bearing-faces 6 to bear against the upper surface ofthe rail and narrow bearing-surfaces 6 to bear against the side of therail-head.

In practice the brackets 4 are disposed so that their slideways 4 makean angle of approximately forty-five degrees, more or less, to thehorizontal, so that as the carrier 5 is moved down to apply thebrake-shoe to the rail such application will be made with a force thatacts to the requisite de ree on both the top and side faces of the railsimultaneously. The brake-shoe carrier 5 has ears 5, to which atoggle-link 8 is pivoted on the bolt 8, and the link 8 has its upper endbifurcated to receive the end 9 of a second toggle-link 9. The links 8and 9 are pivotally connected together by a pivot-bolt 10, as indicated.The link 9 has its upper end 9 pivoted at 9 to a fixed portion of theframe of the truck. The brake-operating rod 11, which is controlled inany approved manner, (not shown,) has its end 11 fulcrumed on the bolt10. As force is applied to move the operating-rod l 1 in the directionof the arrow in Fig. 3 the carrier 5 will be forced downwardly towardthe rail 3 and the brake applied, and when the rod is moved in thedirection opposite to the arrow in Fig. 3 the carrier will be moved andthe brake released.

In the modified form of my invention (shown particularly in Figs. 5 and6) the direction of motion of the rod 11 to apply the brakes is oppositeto that shown in the other figures of the drawings, (see arrow in Fig.6,) and in this form of my invention the carrier 5 is of a differentconstruction than in the other form of my invention. In the modifiedform of my invention the carrier 5 is pivoted at 5 to suitable ears 1 ofthe truckframe, and the carrier also has ears 5*, to which the link 8connects, as before. Thus it will be seen that when power is applied tothe rod 11 to move it in the direction of the arrow in Fig. 6 thecarrier 5 will be moved on its pivot 5 and the brake-shoe applied to therail, as before. WVhen the rod 11' is moved in the direction oppositethe arrow in Fig. 6, the brake will be released.

It should be understood that a brake -mechanism is mounted on each sideof the truck, so as to engage each rail, and I preferably mount themechanism in transverse alinement and preferably between the front andrear wheels of the truck. While I have mentioned the brake devices asbeing applied to a truck, yet I desire it understood they may be appliedto any part of the car or vehicle-body where it may be found convenientto do so, although when usedon railways and the like the preferableposition of the brake is on the trucks.

From the foregoing description, taken in connection with theaccompanying drawings, it is thought the complete construction,operation, and numerous advantages of my I invention will be readilyunderstood by those skilled in the art to which it appertains, and Idesire to say that many slight changes in the detailed construction,operation, and arrangement of parts can readily be made withoutdeparting from the spirit of the invention or the scope of the appendedclaims.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, is*

1. The combination with a wheeled truck and a trackway therefor, ofbrackets carried by the truck, a shoe-carrier slidable in said brackets,a brake-shoe having a plurality of track-engaging faces carried by thecarrier, and means for moving said carrier in a direction substantiallyat an angle of forty-five degrees to the horizontal to simultaneouslyapply all brake-shoe faces to the track, substantially as shown anddescribed.

2. The combination with a wheeled truck and a trackway therefor, ofbrackets carried by the truck, a shoe-carrier slidable in said brackets,a brake-shoe having a plurality of track-engaging faces carried by thecarrier, and means for moving said carrier in a direction substantiallyat an angle of forty-five degrees to the horizontal to simultaneouslyapply all brake-shoe faces to the track, said means comprisingtoggle-links secured to the truck and to the carrier and abrake-operating rod connected with the toggle-links, substantially asshown and described.

3. The combination with a wheeled truck and trackways therefor, of abrake-shoe carrier mounted on the truck, a brake-shoe having lugs forentering the apertures in the carrier, and means cooperating with thelugs for securing the shoe on the carrier, toggle-links pivoted to thecarrier and to a fixed part of the truck, a brake-rod connected to thetoggle-links, the carrier and its connection with the truck havingprovisions, in virtue. of which, as the toggle-links are moved by thebrake-rod in one direction, the shoe will be applied to the rail by aforce acting at substantially an angle of forty-five degrees to thehorizontal to apply the shoe to the top and side faces of the railsimultaneously.
